or rachets thereon and when not in use said 10 bolt may be swung backward away from the upper sash and leave both sashes free for movement.

These and other details of the invention are more fully described in the following specification, set forth in the appended claims and shown in the accompanying drawing, wherein:

Fig. 1 is a detail cross sectional view through the two locked sashes.

Fig. 2 is a side view of a detail fragment of 20 the two sashes with the bolt engaged.

Fig. 3 shows the bolt disengaged leaving the sashes free.

Fig. 4 is a fragmentary view showing how a rack may be used.

25 The improved bolt 5 is used connecting the two sashes to primarily prevent the raising of the lower sash or to hold the upper sash so that it cannot be lowered by burglars or outsiders gaining admission to a house through a window.

30 The bolt 5 is hinged at its lower end in the uprights 5 having a base 7 that is adapted to be secured to the top of the lower sash 8 and adjacent a companion upper sash 9 both adapted to move in the usual guides of a window frame.

35 The bolt 5 above its pintle ID has a loose washer H and near its upper end a washer l2 retained in place by a cross pin l3. Between the two washers H and I2 is a coil spring I4 under compression and forcing the washer ll downward and against the upper ends of the uprights 6 so that the tension of spring M will hold the bolt in any position that it may be swung, as for instance in either of the positions shown in Fig. 1 or 3. 5

When it is desired to release the windows the bolt is swung backward either to a vertical or a horizontal position as may be desired and instead of marring the upper sash by the sockets l5 a strip of metal 56 may be secured to the 10 side of the upper sash and have rack teeth for engagement by thebolt.

It is obvious that the parts may be otherwise modified or arranged without departing from the essential features above described or from the scope of the appended claims.

What I claim as new is:

1. In sash locks, the combination of a fork,

a base for said fork and adapted to be secured to a window sash, a bolt pivoted in its lower end in the fork, a washer secured at the outer end of the bolt, a loose washer impinging the fork adjacent its pivot, and a spring confined between the washers and adapted by pressure to retain the bolt in a desired position.

2. In sash locks, the combination of a fork having a base adapted to be secured to upper bar of a window sash and said fork having its free ends flattened on three sides, a bolt pivoted within the flattened ends of the fork, a loose 0
